Letters Patent No. 90,680, dated June 1, 1869.

AIlillPIROVl-LD WAGON-SEAT.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.:

Be it known that I, JOHN H. NALE, of Decatur, in the county of `Macon,and State. of Illinois, have invented certain new and useful'Improvements in the Construction and Arrangement of Springs for Wagon-Seats; and do hereby declare that the following is a full, clear, andexact description of the same, reference being had t0 the accompanyingdrawing, making a part of this specification, in whiche Figure l is afront elevation,

Figure 2 is an end elevation, and

Figure 3, a plan view of the bottom of the seat and springs. f

Letters of like name and kind refer to like parts in cachot' the -guresThe nature of my invention consists in the combination and arrangementof wooden springs beneath the seat, by means of which great elasticityand durability are combined with cheapness, and also in the employmentof adjustable supports between the seat and springs, by whichthestrength of said springs, with reference to the seat, can be soadjusted as to correspond with the weight which said seat is designedt'o ,SUPPONL Y In the annexed drawing- A represents a wagon-seat, ofusual construction,

having secured laterally upon its under side, near the ends, twocross-pieces, of hard woo'd, a a, one inch in thickness.

Secured to the under side of the cross-pieces, near their ends, are twospring-slats, of hard, tough wood, B B, which extend lengthwise beneaththe seat, and furnish a bearing for other spring-slats, C O, which arepivoted. at their inner ends, to the outer side, near the centre,lengthwise of the slats G (l, and extending outward beyond the ends ofthe seat, are joined together in pairs, by means of a cross-piece, E.

Between the bottom of the seat A and each springslat G O, is a block, D,which furnishes a direct bearing for said seat upon said slats, andserves as a fulcrum, by means of which theyjact as levers upon the slatsC O.

' It will be seen that by this arrangement the depression of the seatoperates upon' the springs in athreefold man'ner: rst, the spring-slatsB B, being secured to saidseat at their ends, any change in theposition,

vertically, of said ends, if their centre issupported, will cause themto act as springs; second, the outer ends of the slats O C beingsupported upon the wagonbox, and their inner ends being secured to theslats B B, the weight of the seat resting upon said slats D D, betweentheir points of support, will convert said slats into springs; third,while `the tendency of the slats B of the springs will vary with theposition of said supports or blocks, so that, if they are madeadjustable lengthwise of the seat and springs, a heavy or light load forsaid seat can be provided for.

The latter result is accomplished by means of a series of holes in the,bottom of the seat, into which a pin, passing through the blocks, iscaused to fit, rendering it only necessary to remove said block and pin,and insert the latter in another hole, when it is desired to change thetension of the spring.

This construction and arrangement of springs possesses many advantages,among which are durability, elasticity, adjustability, and cheapness,which will undoubtedly make it very popular.

Having thus fully set forth the nature and -merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is- M Thecombination and arrangement of the springslats B B and O O, and thesupports D D, Ste., with the seat A, substantially as and for thepurpose shown and described.

' Also, the employment `of the adjustable blocks D D, &c., incombination with the seat'A and springslats O O, Src., for the purposeof increasing or lessening the tension of said springs, substantially asherein described.

'JOHN H. NALE.
